Add disposable OpenShift targets to Jenkins custom tests

[razvan]

Description

Requires: #566

Enable everyone to run integration tests on OpenShift by adding new targets to custom integration tests in Jenkins.

Possible new targets:

• replicated OKD clusters
  • advantages: new versions are quickly available, easy to use CLI, fast setup-time
  • disadvantage:
    • it's not a turn key alternative to OpenShift because things are not quite integrated and available out-of-the-box. Example: pull-tokens are missing, the image registry is not properly set up.
    • currently faulty operator installations cannot be cleaned up properly due to caching
• OpenShift on Azure (ARO)
  • advantages:
    • very well integrated. RH operator catalogs already available, UI available
    • shared storage class already configured
  • disadvantages:
    • takes a long time to set up a new cluster (~45minutes)
    • only old (stable) versions of OpenShift are available
• Self-hosted OpenShift/OKD (optional) - just use a cloud provider to start up machines and install OpenShift/OKD ourselves.
  • disadvantages:
    • complicated and error prone
    • needs maintenance from us
• ROSA (OpenShift on AWS) - optional
  • advantages/disadvantages: TODO

Tasks
